Peanut Butter Cookies

This is one of my favorite cookie recipes from the Better Homes and Gardens New Cook Book.

1/2 cup peanut butter
1/2 cup sugar
1/2 cup brown sugar
1 egg
1/2 teaspoon vanilla
1 1/2 cups flour
3/4 teaspoon soda
1/4 teaspoon salt

Thoroughly cream butter, peanut butter, sugars, egg and vanilla.  Sift together dry ingredients; blend into creamed mixture.  Shape in 1-inch balls; roll in granulated sugar.  Place 2 inches apart on ungreased cookie sheet.  Crisscross with fork tines.  Bake at 375 degrees fro 10 to 12 minutes.  Cool slightly; remove from pan.
